Course FAQ
Yes. The Full-Stack Web Development Bootcamp and the Web Development Freelancing course both start from absolute first principles and assume no prior coding experience. The AI-Powered Web Development course is written for developers who already ship code, and states its prerequisites on the course page before you buy.
Not for the beginner courses. You need a computer with an internet connection, a code editor, and the willingness to build things that do not work yet. If you have never written code before, start with the Full-Stack Web Development Bootcamp.
Completely. There are no live sessions, no cohort schedule and no deadlines. Lessons are unlocked the moment your purchase is confirmed and you can work through them in any order you prefer, on any device.
Yes. Every purchase is a one-time payment for lifetime access to that course, including future updates to its lessons. We do not run subscriptions, renewals or automatic charges.
